If a residue of glucose in glycogen is removed from the glycogen molecule and then allowed to proceed through glycolysis to pyruvate, what is the net production of ATP?

Question

Quizplus · Accepted Answer

When glucose is released from glycogen, it is in the form of glucose-1-phosphate, which is converted to glucose-6-phosphate without the use of ATP. In glycolysis, glucose-6-phosphate yields a net gain of 3 ATP (since 2 ATP are produced per glucose molecule, but only 1 ATP is consumed in the conversion of glucose to glucose-6-phosphate).
